Specification of Letters Patent.

Application filed December 28, 1917. Serial No. 209,205.

To all whom it may concern:

Be it known that I, JOHN KIRso BAUM, a citizen of the United States,residing at WVaterbury, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in InvertedIncandescent Gas-Burners; and I do hereby declare the following, whentaken in connection with the accompanying drawings and the characters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this application,and represent, in I Figure 1 a view in side elevation of an invertedincandescent gas-burner constructed in accordance with my invention.

Fig. 2 an enlarged view in transverse section on the line 2-2 of Fig. 1.

Fig. 3 a detached broken view partly in elevation, and partly invertical section, showing the inner end of the goose-neck, and thebearing-sleeve.

Fig. 4 a detached view in elevation of the bearing-s1eeve.

Fig. 5 a detached view of the inner end of the goose-neck.

Fig. 6 a detached edge view of the disklike gas-check prior to itsinsertion into the bearing-sleeve.

My invention relates to an improved inverted incandescent gas-burner,the object being to provide a simple, convenient and effective fixtureof the character described.

IVith these ends in view, my invention consists in an invertedincandescent gasburner having certain details of construction as will behereinafter described and pointed out in the claims.

In carrying out my invention, as herein shown, the goose neck 3 isformed at its inner end with a straight trunnion 4 provided with threeequi-distant, oblong, axially arranged, rectangular air-ports 5 whichco-act with three complementary air-ports 6 in an upstandingbearing-sleeve 7 formed upon its lower end with an integral concentricannular bead 8 from which an integral concentric, internally threadedmounting or conpling-nipple 9 depends. The difference in diameterbetween the bearing-sleeve 7 and the coupling-nipple 9 results in theproduction of a horizontal bearing-shoulder 10 for the support of adisk-like gas-check 11 having a central perforation 12 and initiallyproduced in concavo convex form, as shown in Fig. 6, to adapt it to bepassed downward through the sleeve 7 so as to rest upon the shoulder 10after which it is flattened so as to increase its diameter, and cause itto fit snugly within the bead 8. The trunnion 4 aforesaid, fits into thesleeve 7 with an airtight friction fit. By swinging the gooseneck to theright or to the left, the ports 5 and 6 co-act to regulate the amount ofair admitted into it. As shown, the goose-neck is provided at itsthreaded outer end 13, which is parallel with its trunnion 4, with ashade-holder comprising three arms 14: supporting a shade 15 inclosing amantle 16. My improved goose-neck burner is mounted upon an ordinarygas-fixture 17 upon which the coupling-sleeve 10 is screwed.

I claim 1. In an inverted incandescent gas burner, the combination witha swinging goose-neck provided at its inner end with a trunnion havingone or more air ports, of a normally stationary upstandingbearing-sleeve receiving the said trunnion with a friction fit andhaving one or more complementary air-ports which are opened and closedby the rotation within the said sleeve of the said trunnion due toswinging the said goose-neck, and the said sleeve being provided with adepending couplingnipple, and a gas-check interposed between the saidsleeve and nipple.

2. In an inverted incandescent gas burner, the combination with aswinging goose-neck provided at its inner end with a trunnion having oneor more air-ports; of an upstanding bearing-sleeve receiving the saidtrunnion with a friction fit and provided with air-ports complementingthe air-ports Patented Nov. 5, 1918.

thereof, the said sleeve being formed at its In testimony whereof, Ihave signed this lower end with a concentric annular bead specificatlon1n the presence of two subser1b- 10 for the reception of a gas-cheek,and the said 111g wltnesses.

bead bein formed with a depending internally th readed coupling-nipplesmaller in JOHN KIRSOHBAUM' diameter than the said sleeve for theproduc- Witnesses:

tion of a bearing-shoulder upon Which the A. C. BECKER,

gas-check rests. J. S. NEAGLE.
